You (Tengen) currently came back from your usual job; fighting demons, such as that, and you were finally able to rest after a long, hard day.

You decided to sit on the couch, watch some TV and have a nice drink. You didn't even know that Hinatsuru, Makio, and Suma were there.

And obviously, your three wifes convinced you to buy them a cat, so you did. And it was sitting on your lap as you pet it.
